My Recycled Bird Scarer

I got the idea from the weekly Garden News and have added the shiny bits on thinking the birds will see them sparkling as they spin. A few of the more experienced gardeners on the allotment site have mixed reservations but if nothing else its a talking point as well as recycling plastic bottles.
If anyone wants me to go into a bit of detail about them I will be happy to oblige.
The image is in my back garden not allotment btw it was my trial bird scarer.
Thanks
